Strong Data Again

Posted by Jeff Id on March 30, 2020

I’m not sure why so many of one political party want to say that hydroxychloroquine azythromycin is only anecdotally effective.   Maybe they don’t know what that word means.

Anyway, here is another strong study but the only control subjects are the rest of the entire planet so maybe that’s not enough.

 

 

Very, very angry at our mindless fascist authoritarian Michigan governor for banning the use of these drugs.  We deserve the right to try.

    Jeff, if as a graduate student I had reviewed the Philippe Gautret et al. paper (available here as #2), I would have said it was a crummy study. However. That would be judging it by “normal” standards, such as expecting such an important finding to be done as a Randomized Clinical Trial, with controls carefully selected to match those getting the Experimental treatment.

    In one of his interviews last week (in French, and I forget which one), Dr. Raoult explained that he would not do this, because he considers it to be unethical under the circumstances. He is a physician treating sick patients, and he considers it his duty to treat them as best he can — and he believes that hydroxychloroquine and azithromycin is by far the most effective treatment for them. Given that — how could anybody expect him to act otherwise?

    In some news articles, I’ve seen him portrayed as a cowboy, or washed-up hippie, or a peddler of phony elixers. I checked his publication record, he’s a genuine physician-scientist who’s been studying infectious diseases, mostly tropical, for decades.

    Like you, I am very hopeful that this combination therapy can be effective — not in every situation, but to help many infected patients. And possibly as a prophylaxis for health care workers. Proof will only come when other doctors reproduce Dr. Raoult’s work. If it is as effective as it seems, they, too, will be challenged to build a gold-standard RCT in the midst of a pandemic.

    Fingers crossed.

      The in-vitro studies at WUWT confirm that the concentration of the hydroxycloroquine at the cell walls determines whether the drug will be effective. The study which went for only 5 days and failed was stupidly performed. They didn’t even attempt to match the in-vitro successful results but instead ran too low of a dosage of the drug. The french doc understood this from the beginning and in the first study, gave rather high doses including a starting bolus to get the concentrations high enough very quickly. This stuff is working very, very well when used correctly. If you or your family ends up being prescribed this drug, make sure you do your math and insist that the doctor give the same levels as the French study. MD’s aren’t paying close enough attention to the literature to understand these minutia – as evidenced by the failed study.

      Belgium has it as a standard procedure, unfortunately combined with other potential treatments that have much less data: https://epidemio.wiv-isp.be/ID/Documents/Covid19/COVID-19_InterimGuidelines_Treatment_ENG.pdf

      The publisher’s statement today disavowing the Gautret et al. paper seem to be an endorsement of the objections outlined in this reply to the paper.

      “Statistical evidence for the positive effect model ranged from strong for the original data, to moderate when including patients who deteriorated, to anecdotal when excluding untested patients, and to anecdotal negative evidence if untested patients were assumed positive.”

      • Jeff Id said

        That reanalysis isn’t very good. Some of the negative assumptions and the focus on them seem a bit contrived. Complaining about the wide range of possibilities where most of the range is in the positive result range is a little silly. It’s become a political game so I trust none of this stuff.

        I’m still waiting for the good ones to arrive, but the in-vitro studies appear very solid so I have high confidence still that we will see good news from them.

    If something shows potential, doctors are going to try it. Why politicize it? There are several candidates right now and medical professionals are not going to hide it from us because of their political persuasion. For this person, they tried hcq+A, then moved on to other things as the condition didn’t improve. He’s now out of ICU and we won’t know what works either.

      Good luck riding out the storm. Hope those who criticized my arguments in support of the 2009 bailout here see the merits of Govt support in a crisis now.

    • Jeff Id said

      It sounds like they are using hydroxychloroquine and azytrhomycin in New Orleans across a lot of people. If the stuff works, I expect we will hear very good news soon.

    • RB said

      1st patient in NJ, a Chinese-American PA:

      “Everybody use medication too late for patients in the United States. Chinese experts suggest to use hydroxychloroquine or chloroquine right after diagnosis not when patient gets worse and virus already spread in the lung. Remdesivir may work the best before ARDS (right after 2nd Worsening chest CT)”

      • Jeff Id said

        That is starting to sound like a consistent theme.

      • RB said

        Former FDA commissioner Scott Gottlieb:
        THREAD: One piece of non-scientific evidence that would nonetheless inform discussion on hydroxychloroquine in the proposed treatment of #COVID19 would be a survey on how widely it was already being used in U.S., Italy, and some other countries, long before current debate. 1/3
        Doctors have been using it widely in U.S., often in combo with azithromycin, since very outset. They used it based on a theoretical potential for benefit, the fact that it was widely available, and a perception that side effect profile is understood so risk/reward favorable 1/2
        Anyone who believes it needs to be “made available” should be assured that it is available, and has been widely used for months all around the world. If the drug combo is working its effect is probably subtle enough that only rigorous and large scale trials will tease it out 1/3
        Ultimately to meaningfully impact outcomes in current crisis, and reduce the risk of future epidemics, we’re going to need highly active medicines. We should be focused on getting these agents with a deliberate effort to support the leading drug candidates

    I’m not a clinician, so this is a spectator sport. In the worst way, as people’s lives hang in the balance.

    Here is a Twitter thread from front-line doc Leora Horwitz in NYC, on 3/30/20 she wrote, “Our standard protocol right now is azithro/hydroxychloroquine/zinc but I have little faith in efficacy. For the patients I really worried about (fast O2 requirement rise, high inflammatory markers) I gave tocilizumab off label. Clinical trial of sarilumab starting this week.”

    Is she faithfully replicating the protocol that Didier Raoult is using at ICH in Marseille? I don’t know. That hospital’s updated tally is 1,524 Covid-19 patients treated… with 1 fatality.

    Some solid data from St. George Hospital in Beirut, Lebanon. On Facebook (3/31/20), treating physician Eid Azar shows primary data on viral load… it decreased for each of 5 patients being treated with hydroxychloroquine and azithromycin, presumably using Raoult’s protocol.

    Hope this (or another) therapy proves out!

      I inserted the wrong comments. David Lat:
      ——————-
      “In these patients, a drug similar to clazakizumab showed promise as an effective treatment for PATIENTS WITH RESPIRATORY FAILURE WHO WERE LIKELY TO DIE.”

      He agreed; I got the drug (along w/tocilizumab).

      I was also given Kevzara, hydroxychloroquine plus azithromycin, and Remdesivir. Which worked? Who knows!

      I believe the only antimalarial is hydroxychloroquine (using along with the antibiotic azithromycin). Kevzara, Tocilizumab, and Clazakizumab are IL-6 inhibitors (anti-inflammatory – e.g., for rheumatoid arthritis). Remdesivir is antiviral.

    French study expanded to 1000 patients. This is only the abstract but very positive news.

    New paper on VA saying hydroxychloroquine alone caused more deaths and when combined with Azythromycin no effect.

    Click to access 2020.04.16.20065920v1.full.pdf

    It’s a terribly difficult paper to accept as medications were applied at different times and amounts. The study is non-random from the VA electronic records. The drugs may have been used only for the worst cases which would skew the entire thing and I can’t figure that out from the data as presented. Waiting until the virus is in the cells is not intended by any of the in-vitro or early human studies to be the preferred use. Of course the media is all over it. Statistical work is convoluted as well.
